In the article titled ?Evaluating the Hemodynamical Response of a Cardiovascular System under Support of a Continuous Flow Left Ventricular Assist Device via Numerical Modeling and Simulations? , there were errors in equations (4) and (7) that should be corrected as follows: (1) In equation (4), the left ventricular volume change (dVlv/dt) was described as the difference between flow rates through the mitral valve (Qmv) and aortic valve (Qav): In equation should be as follows: dVlv dt = Qmv - Qav. (4) (2) In equation (7), the HTA model and the circulatory system model were combined to simulate the CFLVAD assistance using the equations which describe the left ventricular volume change (dVlv/dt) and systemic arterial pressure change (dpas/dt). In equation should be corrected as follows: dVlv dt = Qmv - Qav - QHTA, dpas dt = Qav + QHTA - Qas Cas . (7)equations were used correctly in the computations and errors appear only in the text.
